Do the "experts" say this sounds the same as the 1965 version? I don't know. Sounds the same to me, but I am no expert. It has not been redesigned. Just re-released as a product. Same cabinet design, same Jensen "special" speakers, same tube pre-amps, reverb drivers and 6L6 output stage. I have another, solid state Fender "Stage 1000" that has digital signal processing, etc. Sounds ok, but not like the tube twin. There isn't a chip, processor or digital circuit in it. Eisboch Does it have the original tube rectifier, or the later replacement? Hold on .... I'll check .... Must be a solid state (brick) rectifier. It has 10 tubes total .... (4) 6L6's, (2) 12AT7's, (4) 12AX7's. Ah - now you ruined it. Solid state - bleeeech.... :) What does a full wave, solid state bridge recifier have to do with the sound of the preamps and power amps? All it does is supply clean B+ and bias voltages to the grids? I'll bet the solids are cleaner, DC wise, than the tubes. Eisboch Yes, and solid state pre amps and power amps are cleaner than tube amps, as well. Clean and accurate reproduction is not necessarily the objective with tube amplifiers for musical instrument amplification. How the power is delivered to tubes can measurably affect things such as rise time and decay. I'm not promising that you can actually hear the difference, but purists will swear they can even if it is a physiological impossibility. |

If you think about it though, the "power" is really being delivered by one or more big filter capacitors. I never asked one if it cared how the power got there. At that point, DC is DC. Eisboch |

Eisboch You would think so, wouldn't you! Bear in mind that a vacuum tube is a mechanical structure and not all of the power is part of the signal path. You have to account for uneven heat, vibration and other anomalies that all go into what come out. The vagaries of a wimpy, tube rectified power supply, with hand rolled paper caps should not be underestimated. Purists will also insist that point to point wiring sounds different than circuit board construction. They may be right about that in some cases. Sounds crazy, though... |

I'll buy into the point to point wiring. An important critera used in high quality tube amps was to design the chassis so the signal wiring was as far away as possible from the power wiring. And, if you noted any funny noises or distortion, you could always re-route the wires. As for the power supply, I am still not convinced a tube rectifier is going to sound (or display on an O'scope) any different than solid state, if measured at the filter stage or any B+ test point. The audio amplifiers certainly are different between solid state and tubes and that is readily noticeable, even by people with tin ears. But 300 volts DC? Eisboch |

However, I can tell the difference between, say, my Mac 50s and a similar power level solid state monoblock. And I know others who can. So there must be something to it. Maybe it's all in our heads. Mine's certainly empty enough. :) |
